over cables or an up-link port.
â™¦ Store-and-forward switching scheme capability to support rate
adaptation and ensure data integrity.
â™¦ Auto-polarity detection for correction of incorrect polarity on the
receive twisted pair at each port.
â™¦ Data forwarding rate 148,800 pps per port at 100% of wire-speed
for 100Mbps speed.
â™¦ Data forwarding rate 14,880 pps per port at 100% of wire-speed
for 10Mbps speed.
â™¦ Data filtering rate eliminates all error packets, runts, etc. at
148,800 pps per port at 100% of wire-speed for 100Mbps speed.
â™¦ Data filtering rate eliminates all error packets, runts, etc. at
14,880 pps per port at 100% of wire-speed for 10Mbps speed.
â™¦ Up to 4K unicast address entities per device, self-learning, and
table aging.
â™¦ 256K Byte-on-Chip packet buffer per eight ports.
â™¦ All 16 or 24 UTP ports support IEEE802.3x flow control for full
duplex and backpressure flow control for half duplex.
â™¦ Optional two-port Fiber module (SC type connector) in the front
panel for length extension. These two ports operate at either 100M 1 10/100 Fast Ethernet Switch Userâ€™s Guide
full duplex or half duplex by means of a manual setting. Please
see Chapter Two for additional information about module settings. 2 10/100 Fast Ethernet Switch Userâ€™s Guide 2 1 UNPACKING AND SETUP Unpacking Open the shipping carton of the Switch and carefully unpack its
contents. The carton should contain the following items:
â™¦ One DES-1016R+ or DES-1024R+ 10/100 Fast Ethernet Switch
â™¦ One AC power cord
â™¦ This Userâ€™s Guide
â™¦ Four rubber feet with adhesive backing
â™¦ Screws and two L-type brackets for rack mounting If any item is found missing or damaged, please contact your local
D-Link reseller for replacement. Setup The setup of the Switch can be performed using the following steps:
â™¦ The surface must support at least 3 kg for the Switch.
â™¦ The power outlet should be within 1.82 meters (6 feet) of the
device.
â™¦ Visually inspect the power cord and see that it is fully secured to
the AC power connector.
â™¦ Make sure that there is proper heat dissipation from and
adequate ventilation around the Switch. Do not place heavy
objects on the Switch. 3 10/100 Fast Ethernet Switch Userâ€™s Guide Desktop or Shelf Installation When installing the Switch on a desktop or shelf, the rubber feet
included with the device must be first attached. Attach these cushioning
feet on the bottom at each corner of the device. Allow enough ventilation
space between the device and the objects around it.

Figure 2.1 10/100 Fast Ethernet Switch installed on a Desktop or Shelf Rack Installation The Switch can be mounted in an EIA standard size, 19-inch rack,
which can be placed in a wiring closet with other equipment. To install,
attach the mounting brackets on the switchâ€™s front panel (one on each
side) and secure them with the screws provided. 4 10/100 Fast Ethernet Switch Userâ€™s Guide

Figure 2.2 Attaching the mounting brackets to the 10/100 Fast Ethernet Switch
Then, use the screws provided with the equipment rack to mount the
Switch in the rack. Module Installation An optional two-port fiber module (SC type connector) can be installed in
the front panel. Follow these steps: First, set up the module, adjusting the jumper settings as desired. The
default setting is full duplex.

Figure 2.3 Jumper settings on the module 5 10/100 Fast Ethernet Switch Userâ€™s Guide Next, make sure that the device is powered off and then remove the
plain bracket on the front of the switch.

Figure 2.4 Removing the plain bracket
After removing the plain bracket, slide the module in the guide rails all
the way into the slot and secure the screws.

Figure 2.5 Sliding the module into position
When properly installed, the Slot LED will be lit after powering on the
Switch (see Chapter 3 for more information about LEDs, including a
diagram). Note:Always remember to turn off the power before a module is inserted or removed.

â™¦ AC Power Connector This is a three-pronged connector that
supports the power cord. Plug in the female connector of the
provided power cord into this connector, and the male into a
power outlet. Supported input voltages range from 100 ~ 240 VAC
at 50 ~ 60 Hz. 7 10/100 Fast Ethernet Switch Userâ€™s Guide LED Indicators The LED indicators of the Switch include Power, 100M, Link/Act
(Link/Activity), and Slot. The LED indicators are used to facilitate
monitoring and troubleshooting of the Switch. The following shows the
LED indicators for the Switch along with an explanation of each
indicator.

Figure 3.3 The DES-1024R+ Switch LED indicators
â™¦ Power This indicator operates when the Switch is turned on. If
this indicator is not lit, check the AC power connector to ensure
proper insertion of the power cord.
â™¦ 100M The LED indicator lights green when a 100 Mbps device is
connected to a respective port. If a 10 Mbps device is connected to
a respective port, the LED indicator is OFF.
â™¦ Link/Act These LED indicators are lighted greenwhen there is
a secure connection (or link) to a device at any of the ports. The
LED indicators blink greenwhenever there is reception or
transmission (i.e. Activityâ€”Act) of data occurring at a port.
â™¦ Slot This LED indicator is lighted green when there is a secure
connection (or link) to an optional two-port 100BASE-FX (SC type)
module is installed in the front panel. Each port has its own LED,
designated as I and II. See 100M and Link/Act indicator
descriptions above for further information. 8 A 3 TECHNICAL SPECIFICATIONS
